Relating the super domination and 2-domination numbers in cactus graphs
(De Gruyter, 2023)A set D⊆V(G) is a super dominating set of a graph G if for every vertex u∈V(G)\D , there exists a vertex v∈D such that N(v)\D={u} . The super domination number of G , denoted by γsp(G) , is the minimum cardinality among ... -
Relativistic particles with torsion in three-dimensional non-vacuum spacetimes
(American Institute of Physics, 2021)In this paper, we analyze trajectories of spacelike curves that are critical points of a Lagrangian depending on its total torsion. We focus on two important families of spacetimes, generalized Robertson–Walker and standard ... -
La resolución de problemas basada en el método de Polya usando el pensamiento computacional y Scratch con estudiantes de Educación Secundaria
(Universidad de Oviedo, 2020)La inclusión de la tecnología como recurso educativo supone un nuevo escenario de trabajo en el aula que requiere de un proceso de investigación empírica para valorar su efectividad. El presente trabajo consiste en un ... -
Revistas brasileñas de Educación en SCOPUS: un análisis bibliométrico

Rough solutions for the periodic Schrödinger-Korteweg-de Vries system
(Elsevier, 2006)We prove two new mixed sharp bilinear estimates of Schrödinger-Airy type. In particular, we obtain the local well-posedness of the Cauchy problem of the Schrödinger-Kortweg-de Vries (NLS–KdV) system in the periodic setting ... -
Shallow Water Moment Models for Bedload Transport Problems
(Global Science Press, 2021)In this work a simple but accurate shallow model for bedload sediment transport is proposed. The model is based on applying the moment approach to the Shallow Water Exner model, making it possible to recover the vertical ... -
Sharp bilinear estimates and well-posedness for the 1-D Schrödinger-Debye system
(Khayyam Publishing, 2009)We establish local and global well posedness for the initial value problem associated to the one-dimensional Schrödinger-Debye(SD) system for data in Sobolev spaces with low regularity. To obtain local results we prove two ... -
Situaciones Asociadas a los Números Negativos en Textos de Matemáticas Españoles de los Siglos XVIII y XIX
(Junta de Andalucía, Grupo "Didáctica de la Matemática. Pensamiento Numérico", 2007)Se presenta el avance de una investigación sobre la presencia de los números negativos en los textos de matemáticas publicados por autores españoles durante los siglos XVIII y XIX. El centro de atención ha estado en ... -
Some new results on the k-tuple domination number of graphs
(EDP Sciences, 2022)Let k ≥ 1 be an integer and G be a graph of minimum degree δ(G) ≥ k − 1. A set D ⊆ V(G) is said to be a k-tuple dominating set of G if |N[v] ∩ D| ≥ k for every vertex v ∈ V(G), where N[v] represents the closed neighbourhood ... -
Spacelike hypersurfaces with functionally bounded mean curvature in Lorentzian warped products and generalized Calabi-Bernstein type problems
(Cambridge University Press, 2019)We study spacelike hypersurfaces with functionally bounded mean curvature in Lorentzian warped products M = I × f F , where F is a (non-compact) complete Riemannian mani- fold whose universal covering is parabolic. In ... -
Spanish Doctoral Dissertations on the Properties of Materials in Engineering
(Kassel University Press, 2024)We present a bibliometric study of engineering doctoral dissertations focusing on the properties of materials. The study exhaustively examines the production of doctoral theses on material properties in the ... -
Stability of maximal hypersurfaces in spacetimes: new general conditions and application to relevant spacetimes
(Springer, 2017)We obtain new simple sufficient conditions to ensure the stability and strong stability of maximal hypersurfaces (without boundary) immersed in an arbitrary spacetime. Several applications to maximal hypersurfaces in a ... -
Stability of mKdV breathers on the half-line
(Springer, 2022)In this paper we study the stability problem for mKdV breathers on the left half-line. We are able to show that leftwards moving breathers, initially located far away from the origin, are strongly stable for the problem ... -
Stable Minimal Surfaces in Riemannian Warped Products
(Springer, 2017)We obtain several stability results forminimal two-sided surfaces immersed in a wide class of 3-dimensional Riemannian warped products, which includes the class of Riemannian products. As a consequence, some Bernstein-type ... -
